The identified proteins were divided into two following categories: one is regulatory proteins, for example, caffeic acid 3-O-methyltransferas, HSP70, glyoxalase I , actin, and so on. They are involved in protein biosynthesis and processing, cellular structural organization and stress responses. The other is function proteins, for instance, ascorbate peroxidase, cytoplasmic malate dehydrogenase, cytosolic phosphoglycerate kinase, S-adenosyl methionine synthetase, ATP synthase, and so on. They are involved in photosynthesis, photorespiration, redox homeostasis, and metabolisms.
